Description

To run user containers that interact with HiveServer2 in a Kerberized cluster, like Hive Import and Hive Export plugins, the containers will need HiveServer2 delegation tokens. As it does for other delegation tokens, CDAP Master should fetch the delegation token from HiveServer2 and push the token to YARN containers started by CDAP.
